Harvey Pilkenton 2nd marriage

Trying to find information on second marriage of Harvey Pilkenton - born May 20, 1845 (Tenn), died October 16, 1906 (KY).I have him marrying Malinda Hutchinson February 22, 1866.Her tombstone says she died March 23, 1897.

In the 1900 Hardin County census (Sonora) KY, Harvey is shown with Mary T- married 3 years.Does anyone have an exact date as to when they married, Mary's birthdate and maiden name?
